Abstract

In the present study, we investigated the quality characteristic of ginseng cultured in bioreactor system and the optimum recipe condition of the liquid tea using cultured ginseng. The contents of soluble solid and crude saponin in cultured ginseng were 31.8% and 1.94%, respectively, which were lower than commercial ginseng. In the concentrated extract, crude saponin content was 4.77% and the contents of ginsenoside Rc, Re and Rg$_1$were 7.36, 4.40 and 1.75 mg/g, respectively. The ginsenoside Rb$_1$and Rb$_2$, main contents of commercial ginseng, were not detected. The optimum ranges of recipe on organoleptic properties of ginseng liquid tea were estimated on 9.0~10.4% of the extract, 6.8~8.1% of apple vinegar and 40% of fructose. The liquid tea using commercial ginseng showed higher scores of sensory lest than the liquid tea using cultured ginseng in bioreactor system at the given condition, 10% of the extract, 7% ofapple vinegar and 40% of fructose, with the same recipe condition ranges.

본 연구에서는 생물반응기에 배양된 인삼의 품질 특성 및 이를 이용한 액상차 제조에 관한 연구를 행하였다. 생물반응기에서 배양된 인삼 추출물에 대한 품질특성은 가용성 고형분 함량 및 조사포닌 함량이 각각 31.80%, 1.94%로 나타나 재배 인삼보다는 함량이 낮은 경향이었다. 농축액의 조사포닌 함량은 4.77%이었으며 ginsenoside Rc, Re 및 Rg$_1$은 7.36, 4.40 및 1.75 mg/g으로 나타났으며 재배인삼에 많은 함량을 차지하는 ginsenoside Rb$_1$과 Rb$_2$는 검출되지 않았다. 생물반응기에서 배양된 인삼의 활용방안으로 추출.농축액을 이용하여 액상차를 제조하여 최적 배합비를 설정하였다. 액상차제조의 최적 배합비 범위는 농축액 함량 9.0~10.4%, 사과식초 함량 6.8~8.1%, 과당 함량 40%로 예측되었다. 또한 배양 인삼 농축액과 재배인삼 농축액으로 제조된 액상차의 관능적 품질을 재배인산 농축액으로 제조된 액상차의 관능적 품질을 비교하고자 예측된 임의의 조건(농축액 10%, 사과 식초 7%, 과당 40%)으로 동일하게 제조하여 비교하였을 때 관능적 품질은 재배인삼이 생물반응기에 배양된 인삼보다 높은 관능평점을 나타내었다.
